| Summary: | Serious accidents, which occurred in road tunnels in the 2000’s, have revealed specific risks related to tunnels, along with safety management issues. The lessons learned analyses are one resource used by tunnel operators, supported by the French Tunnel Research Centre (CETU), to improve safety management. The question raised in this paper is how these processes are linked to the actual collective safety management. Based on careful analysis of shift handover of tunnel control station operators, we aim to show what makes them a means for sharing feedback, managing safety and building a collective structure. We will thus highlight the strength of communication dynamics to design innovative safety management tools within a high-risk industrial environment.
